Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed December 11, 1908. Serial No. 184,795.

T0 on whom it may concern:

Be it known that I, WILLIAM CLINE, a citizen of the United States,residing at Lancaster, in the county of Lancaster and State ofPennsylyania, have invented certain new and useful Improvements inApparatus for Purifying (Jrases of Combustion, of which the following isa specification,reference being had therein to the accompanyingdrawings.

This invention relates to improvements in that class of devices designedto separate soot and other extraneous matter from the gases that passfrom the fire up through the chimney; and the object of the invention isto permit the free passage to and through the chimney of the gases ofcombustion and at the same time prevent the passage ofv the eXtraneousmatter thrown off by the fire with the gases.

The invention consists in the construction and combination of thevarious parts, as hereinafter fully described, and then pointed out inthe claims.

In the accompanying drawings, forming a part of the specification,Figure l is an elevation of a device embodying my improvements, partsbeing shown in section; and Fig.

' 2, a similar view of a modification of the construction shown inFig. 1. Figs. 3 and 4 are perspective views of one of the revolvingsieves, and Fig. 5 a top plan view thereof. Fig. 6 is a top plan view ofa pair of the cross-bars wherein the vertical shafts are journaled, andFig. 7 a section of the waterwheel chamber transversely of the shaft,and Fig. 8 illustrates a modification in the construction. Fig. 9 is atop plan view of a section of the frame in the bottom of theseparator-flue in Fig. 8, and Fig. 10 a longitudinal vertical section ofsaid frame. Fig. 11 is a top plan view of one of the water-wheels andits pipes shown in Fig. 8.

Similar numerals indicate like partsthroughout the several views.

Referring to the details of the drawings, more particularly Figs. land2, 9 indicates the smoke stack or chimney; 10, the furnace, heater, orstove, and 11 the circular vertical sections of the flue containing theoperating mechanism. In Fig. 1 and the main part of Fig. 2 verticalsections 11 are connected by frustocones 12, the bases whereof extendbeyond the walls of the vertical sections below them and the upper endsof which are of the same diameter as the vertical sections above them,which frustocones form sieve-chambers.

At the top and bottom of each sieve-chamber are cross-bars 13, at theintersection of which are bearings for the vertical shafts 14. Justbelow the upper journal-bearing of each sievechamber there is secured onvertical shaft 14: a water wheel 15, having vertically-disposed buckets.Immediately under each of said water-wheels are cross-bars 16, and abovethe lower journal-bearings are similar cross-bars 17, both being securedto shaft 14:, but crossbars 17 are'longer than cross-bars 16. Thesecross-bars are in pairs, the bars of each pair being disposed at rightangles the one with the other, and the shaft 14: passes through theintersection of each pair of said cross-bars. Attached to cross-bars 16and 17 are spirallydisposed sieves 18, which disposition is obtained byattaching the upper end of each sieve to an end of one of the uppercross-bars 16 andthe lower end to the corresponding end of the cross-bar17 at right angles with said end of the cross-bar 16 and disposed withreference thereto in the direction in'which said sieves will move. Thesesieves are constructed of wire-netting. In the vertical section 11 underthe lowest fan-chamber is located a vertical shaft 19, similar to thoseabove it and journaled in the intersection of cross-bars 20. This shaft19 also has on its upper end a water wheel15,with vertically-disposedbuckets, and on said shaft 19, below the water-wheel, is secured aspirally-disposed plate 21, forming a suction-fan, as shown in Fig. 1.

Shaft 19 passes through and extends below cross-bar 20 and has on saidextension abevelgear 22, meshing with a bevel-gear 23 on a horizontalshaft 2 1. In Fig. 1 shaft 24 has thereon a pulley 25, connected by abelt 26 with a pulley 8 on a horizontal shaft 27. On shaft 27 is abevel-gear 28, meshing with a bevel-gear 29 on a vertical shaft 30,which extends down to Waste-tank 31. The aforesaid pulleys, belt, andbevel-gears 28 and 29 are all located outside of flue 11 12. Shaft 27eX- tends through a chamber 32, located directly below flue 11 12, andin said chamber and on shaft 27 is a water-wheel 33. The upper end ofchamber 32 is funnel-shaped, as shown at 34:, to receive water from flue11 12 and to feed it to Water-wheel 33 through dischargepipe 35, and inthe bottom of said chamber 32 is an outlet-pipe 36, that discharges intoa water-tank 31.

Connected with the source of supply is an upright water-pipe 37 havingbranches 38 opposite each of the water-wheels 15, and these water to andthrough the wall of the flue above.

the uppermost sieve and discharges it onto said sieve. This is simplyanauxiliary contrivance and is not intended to cooperate with waterdischarged through branches 38.

In operation water is ejected from the branches 38 of water-pipe 37against the buckets of water-wheels 15, causing the sieves and thespiral suction-fan 21 to revolve in the direction of the arrow 43, Fig.5, the movement of said spiral suction-fan being aided by its connectionwith the water-wheel 33 in chamber 32 through the gearing on shafts 19,24,

a and 27. The smoke passes from the furnace,

heater, or stove 10 into flue 11 12, as shown by arrow 44, and the draftin said flue is increased by the suction movement of spiral fan 21 andof the sieves 18. The sieves intercept and hold the extraneous matterthrown off by the fire with the gases of combustion, while the waterfrom branches 38 washes said matter from the sieves and carries itdownward.

In Fig. 2 the vertical section 45 of the flue is located by the side ofthe body thereof and is connected therewith by an elbow 46, and in saidvertical section 45 is located the spiral fan 21. The gearing forconveying power from water-wheel 33 to the spiral fan 21 is modifiedaccordingly. The shaft 47, on which said water-wheel 33 is mounted, hasa bevelgear 48, meshing with the bevel-gear 22 on shaft 19, and belowsection 45 is a basin 48, having adischarge-pipe 49, that empties intothe outlet-pipe 36. V

In Figs. 8, 9, 10.,and 11 is illustrated a further modification in theconstruction whereby the products of combustion and the water forseparating, the extraneous matter from the gases of said products passin the same direction through the flue leading to the smoke-stack, inwhich flue the extraneous matter is separated from said gaseous productsand prevented from passing to the smokestack. In these figures, 66 isthe fire-box; 67 ,a boiler; 68, the separator-flue; 69, the smoke-flueleading from the fire-box to the top of the separator-flue; 7 0, thesmoke-stack, and 71 the passage between the bottom of the separator-flueand the smoke-stack. 72 is a vertical shaft journaled in the ends ofarms 73 of brackets 74 and 75, respectively, attached to a wall ofseparator-flue 68, bracket 74 being located below the opening leadingfrom smoke-fiue 69 into said separator-flue 68 and bracket 75 adjacentto the passage 71 between the separator-flue and the smokestack. Onshaft 72 are rigidly secured a plurality of spirally-disposed platesforming fans 76, adapted to draw the products of combustion fromsmoke-flue 69 into separator-flue 68 and to force said products down theseparator-flue. On shaft 72 are water-wheels 77, whereby said shaft 72is actuated. Motion is imparted to water-wheels 7 7 by water ejectedagainst one side of each through a branch pipe 78 and against the otherside by a branch pipe 79, both said branch pipes for each ofwater-wheels 77 extending from the same joint 80 connecting them withvertical supply-pipe 81, branch pipes 79 curving around the sides of thewater-wheels, as shown" in Figs. 8 and 11. 82 indicates the exhaustpipe,extending down the outside of separator-flue 68 and having an arm 83thereon extending into said separator-flue. The inner end 84 of arm 83is turned downward and discharges into a sprayer 85, which it supports.Above and extending entirely over the bottom 86 of separator-flue 68 isa frame 87 having side and end bars and legs or feet 88. Transversely ofthis frame are sloping slats 89, having their ends secured in the sidebars of said frame, the lower edge of each of these slats extendingbeneath the upper edge of that adjacent thereto, as shown in Fig. 10.The outer end of the flue-bottom 86 is sloped upward, as shown at 90,and in the center of said bottom is a discharge-pipe 91.

In operation the products of combustion are drawn downward throughseparator-flue 68' by fans 76 and the discharge from exhaust-pipe 82,while the water from branch pipes 78 and 79 and said discharge fromexhaust-pipe 82 washes the extraneous matter from the products ofcombustion and carries it down onto slats 89, from which it is washeddown to and through discharge-pipe 91,-

while the gases of combustion pass to and up smoke-stack 7 O. Thesloping and lapping of slats 89 prevents the uprising of said extraneousmatter.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-
